  • COVID-19 Critical Infrastructure Cyber Threat Brief
    Digital Intelligence Securing the Future COVID-19 Critical Infrastructure Cyber Threat Brief CLIENT CONFIDENTIAL Cyjax Purpose This Cyber Threat Brief is intended to help mitigate the risk of cyberattacks against UK critical infrastructure during the coronavirus pandemic. We have defined critical infrastructure as: food supplies, medical supplies, transportation, security services, telecommunications, utilities and financial services. This report provides a broad overview of all relevant coronavirus-related digital threats, alongside more general vulnerabilities that attackers could exploit. We at Cyjax hope this will help organisations and their staff protect themselves from digital threats during this national crisis. If you require any further assistance or advice, please contact us. Overview of malicious cyber activity We have witnessed a significant uptick in cyberattacks exploiting fear of the coronavirus to compromise victims. Notably, however, there has not been a surge in the total number of attacks. Instead, existing cybercriminal operations have been rethemed with COVID-19 lures. Attackers have not gained more resources, but are instead repurposing their existing phishing, ransomware, and malware infrastructure to include COVID-19-themed keywords in a bid to infect more users. [1] All sectors are being targeted with COVID-19-themed attacks, including those operating in the critical infrastructure space. Attacks have ranged from generic “spray and pray” attacks to highly targeted advanced persistent threat (APT) operations. A broad array of nation-state actors have been involved from China, Russia, North Korea and Iran, among others. Sophisticated cybercriminals are also staging coronavirus-themed attacks. Most notably, organised ransomware gangs, who have continued to compromise, encrypt and leak data from a diverse group of organisations.

  • Global Threat Report Mid-Year 2021 Introduction
    Global Threat Report Mid-Year 2021 Introduction Threat actors are constantly adding to their repertoire by exploring new tactics and techniques to help bolster their efficacy against both technological blockers and humans. So far, this year has been no different as they have continued to add new methods to their toolchest. Thus far in 2021, we have observed several new techniques in the realm of customization as well as obfuscation. We will cover several examples in this report. We will also examine several consistent attack trends that continue to plague organizations across the globe. We are halfway through 2021 and one thing remains unchanged - email is still the number one attack vector for infecting organizations globally. Through the first half of 2021, phishing attacks continued their evolution with greater levels of sophistication. For the first time we observed attackers leveraging real web certificate data to add credibility to their attacks through customization. We also observed greater levels of obfuscation as some attacks threat actors went to great lengths to disguise the nature of their attacks. We observed phishing attacks leveraging CAPTCHA technology to avoid detection. Threat actors also continued the cycle of abuse by leveraging legitimate services to hide their intent. Job seekers and hiring functions within organizations were also targeted with phishing emails designed to mimic legitimate job sites. IC3 recently reported Business Email Compromise as the costliest of cybercrimes in 2020 with adjusted losses totaling $1.8 billion. It is not surprising we observed a large and growing volume of BEC attacks throughout Q1(’21) and Q2(’21) which show no signs of abating.

  • Security Now! #789 - 10-20-20 Anatomy of a Ryuk Attack
    Security Now! #789 - 10-20-20 Anatomy of a Ryuk Attack This week on Security Now! This week we examine the coming controversial changes to the WebExtension API. We look at the revelations and fallout from last week's Patch Tuesday, and at Zoom's latest announcement of this week’s roll-out of end-to-end encryption. We make sure everyone knows about the latest horrific SonicWall vulnerability and Microsoft's pair of not-that-worrisome out-of-cycle patches. We share a bit of miscellany and closing-the-loop feedback. Then we examine an actual Ryuk Ransomware intrusion and attack... step-by-step. Browser News Edge to be updated with browser extensions “Manifest V3” The proposed changes to the WebExtensions API, generically known as “Manifest V3” were first announced by Google two years ago, in October 2018, for its Chromium project. And as we'll recall, Google's stated plans did not go over well. When Google announced their planned changes they said that the main intent was to improve extension security, improve extension performance and give users greater control over what extensions did and with which sites they could interact. But extension developers quickly pointed out that the “Manifest V3” updates contained changes that crippled the ability of ad blockers, antivirus, parental control enforcement, and various privacy-enhancing extensions to do their job as they had been. As a consequence, Google's announcement triggered a significant backlash from users, extension developers, and even other browser makers. Since, among other things, the extensions had the effect of limiting the power of ad blockers to block ads, the non-Google community was unhappy to see Google — an advertising-based company — moving to limit our ability to limit the ads our browsers subjected us to.

  • Maze & Ryuk Ransomware Threat Assessment Report
    WHITEPAPER MAZE & RYUK RANSOMWARE THREAT ASSESSMENT REPORT TRU THREAT RECONAISSANCE UNIT Where we are right now INTRODUCTION Ransomware first entered the scene as a serious and categorical threat in May 2017. Since then, the new category has been an incredible money-maker for threat actors and multiple variations have been iterating non stop ever since. Chief Information Security Officers (CISO’s) and security teams across the globe have focused their efforts on detecting and deterring these destructive attacks. One trend, however, appears to be certain: Ransomware is here to stay, and both the virulence and velocity of these attacks are on the rise. Two new strains of Ransomware appear particularly troubling. Security On-Demand’s Threat Reconnaissance Unit (TRU) has published this Threat Assessment Report in an effort to help educate our community on better identifying indicators and providing guidance on a strategy to counter-act this threat. Unlike typical ransomware, which contain many behavioral commonalities in terms of how it proliferates, the Ryuk and Maze Ransomware strains are changing the landscape and we believe it to be a cause for concern as a new chapter unfolds. Let us examine the Ryuk Ransomware first. Ryuk Proliferation At this point in the lifecycle of a traditional THE RYUK ransomware attack, the ransomware would generally execute and immediately start encrypting folders and files. Such rapid execution decreases the likelihood of detection and this RANSOMWARE encryption process may be as quick as 30 seconds or multiple minutes. Regardless, Ryuk Security researchers have attributed Ryuk to is most successful when the device’s antivirus or the Wizard Spider threat group operating out of endpoint protection services failed to identify and Russia and Eastern Europe, which was first quarantine the threat on the endpoint or target observed in October 2018.
